# AT403 and AT9x0 Continuous Scanning Modes

To set the continuous scanning modes for the AT403 and AT9x0 laser trackers:

1. From the Parameter Settings dialog box (Edit | Preferences | Parameters), click the Probing tab.

Parameter Settings dialog box - Probing tab

2. In the Hard Probe Scanning Minimums area, set one or both values:

- Time delta (sec) - Used for Continuous Time mode

- Distance delta (mm) - Used for Continuous Distance mode

3. Click Apply to save the settings and then OK to close the dialog box.

4. From the Tracker Operation toolbar, choose the mode:

Continuous Distance

Continuous Time

5. (Optional) If you are aligned to the physical part and a CAD model, from the Probe Mode toolbar (View | Toolbars), turn on Find Nominals from CAD Mode. This step allows each scanned point to have a nominal value and also allows you to view the hits as they are scanned.

6. From the Quick Start window, select the type of feature you wish to scan (for example, Plane or Scan).

Quick Start window for continuous scan mode

The scan process is: Start the scan, scan the feature, stop the scan, END.

To do this:

- Press Ctrl+I to start the scan and Ctrl+I to stop the scan, or use the Continuous Scan button () on the Tracker Measure toolbar.

- For the AT403 tracker, use the A button on the remote control to start and stop the continuous scan.

- For the AT960 T-Probe, hold down the D button for the continuous scan.

If Continuous Scan mode is not selected, the D button defaults to the Continuous Distance mode.

- When you finish scanning a feature (such as a circle or plane), compensate correctly and then press the END button.

7. Continuous Distance and Continuous Time can also be inserted into the measurement routine as Tracker Commands. During execution, you can Start, Stop, and END the continuous scan as described above.
